About RFSigns.com

RFSigns is the brainchild of Isotrope, LLC co-founder David Maxson.  David has been providing RF exposure management services for over twenty years. With such long and varied experience with broadcasting and wireless facility safety management, it finally dawned on him that there was no one more experienced or more qualified to develop a family of  durable ANSI-compliant RF Safety signs.

Co-owner Steve Riggs has 3 decades of experience managing and maintaining broadcast facilities.  He brings practical day to day experience to RF Safety management.   Steve's been there, out at the tower fence on a cold day, trying to figure out where to put the sign, and how to mount it.

RFSigns' mission is to provide the radio industry with the best, most effective, standards-compliant RF safety communication tools.


RFSigns.com recommends that RF signs be used as part of a comprehensive occupational safety program, including:  hazard communications signage, a written hazard management policy, training, record-keeping, surveys and calculations and the availability of personal protective equipment (PPE) as needed.
